Yb all ur/wm, i2. zuny concern:

lie it lcnomi that we,'ELi.swon'rii B. A. l hvoreu and liomiwo A. ZWOYER. citizens of the lnited States, and residents of Perth .iinboy. county of Union, and State of New .ierscy, have made .1 new and useful Invcn lion in Machines for Making Briquettcs, of which the following is e specification.

Our invention is directed particularly to img'u'ovements upon briquctte-making ma ehincs, sueh are disclosed in prior U. S. putcntsgranted to us as follows-No (367,050, of Jun. 29th. 1901 g No. 676,484, of June 18th, 1501. and No. 718,043, of Jan. 6th, 1903, in which briquettes are molded or formal between two tangentially arranged molding rolls or drums provided with briquctte forming pockets, and it has for itsobjects, first, to so construct rolls or drums of this nature\ that the forming pockets shall all be identically alike in both rolls, and the adjoining walls of the several pockets shall be provided with the shur 'iest possible cutting ethics, all so located in the faces of both rolls that when the two are rotated in the [)IOCGSS of forming briquettes there 'ill be no possibility of compressing'any of the material between the adjoining edges of the pockets in the rolls in ouch manner as to formv ragged edges or flanges on the briquettes, or to cause any unnecessary waste of energy in the applicution of power in thus forming or compressing briquettes. Second, to provide the briquette making rolls of such a machine with :1. novel shape or conformation of pocket adapted to make a briquette having great strength and durability and of equal density throughout its mass; Third. to provide *meaus for udjust-iuent between the rolls whereby in the event of lost motion due to "wear of the driving gear or other ports of the iu'ipuratus said rolls may be so adjusted that the tangential edges of the lmCh'Cishall always be in (exact alinemeut with each other at the points of highest compression; that to say, they shall be in exact: aluieiuent with each other when they are in a plane. passing through them and through the matheu'laticul axes of the two shafts which support the forming rolls. Fourth, to provide novel means for ioeding the material forward to the rolls and in such manner that it'will be equally distributed over thetop surfaceis thereof so es te-produce the best possible effects and prevent any possibility of causing the rolls to exert greater pressure upon the material as it advances therethrough upon any one portion thereof.

Our invention will be fully understood by referring to the accompanying drawings, in

F'gure 1 is a side elevational'view of a briquette making machine embodying our several improvements, in so far asthey relate to the machine. Fig. 2 is a plan view thereof as seen looking at Fig. 1 from the top toward the bottom of the drawings. Figs. 3, 4.5, 6 and 7 are detail views of the means for radially adjusting thetwo shafts which support the briquette making rolls in such manner as to enable one to always maintain the adjacent knife edges of the pockets in direct alinement with each other and in the same plane as themathematiczil aims of their supporting shafts. Fig. 8' is an edge view illustrating the nature of the briquette multing pockets of the rolls and the manner of constructing the some; and, Aig. 9 is a sectional view of the same taken on the line X1-X Fig. 8 and as sccn looking thereat from right to left in the direction of the arrows. Figs. 10 and 11 are plan and edge views of one of our novel briquettes as constructed b'y moimproved briquette making mechine.

In the manufacture of briquette making machines of the roller or drum type in which the briquettc forming pockets are 10- outed in the surfaces tliereof, it is important, flS'pUlIltQd out in the before-mentioned putcuts, that these pockets shall all be identical duplicates and shrill be so related to each other on both rolls or drums that as the material is advanced and the briquettes are. completed there will be the nicest adjustment of the parts so as to effect a clean It is a matter of common knowledge that int hemauufacture ofbriquette making rolls overcome-this objectionable feature.

1 it is not possible to casttwo' briquette mak ing rolls-in suchrnanner'as toobtain the-:relations' of the pockets on their surfaces in the manner-'hereinbefore stated The improved briquctte making-rolls disclosed in the before-mentioned;patents were designed to overcome thisifobjection, so far as possible, and it was with'the intention of effecting more perfect rolls that this feature ofthe' present invention was designed. ,lVe have I 'alsoiascertained that in the use ofbriquette making rolls like'thoseidisclosed in a prior patent No. 718,043, granted to B. A;

Zwoyer, where the material is fed forward directly to; the. rolls from the-hopper, said *materialfrom whichthe briquettes are made i frequently clo or accuinulates at the lower inner edge's 0 the hopper to siich an extent "as to prevent material 'fronixfal'ling into those pockets -at the extreme ends :of the ,roll's, thereby putting. out. of com mission such pockets'and sometimes, also by'reason I of such accumulation, causing the forming of imperfect 'briquettes in ad oining sets of pockets and for the purpose ofovercoming this-1 objectionable feature -we have devised .meansffo'r' equally =distributing'the feedof [the material (Werthetop surfaces \of the rolls so that perfect briqaettesa'realways.

- ends 0 illustrated in Figsz'ti to mm 13 represents a lag orext'eiisi the shape or conformation of a truncated pyramid, the same constituting means for feeding the material forward to the/rolls inshoh -manner as to equally distribute it over the top surfaces thereof. This feeding tube is supported with its lower edges practically 'out of mechanical contact "with the hopper 9 and its structural arrangement is such that by no possibility can there be formed any deposit of the material as it descends throughthe tube, either thereon or on the hopper 10, such an at rangement making it absolutely sure, as we" have ascertained in practice, that the matey rial will be eijenly distributed over the can osed faces of both rolls at'all times, there" y making it possible to utilize all of the briquetteforming pockets on both rolls and to always produce absolutely perfect briquettes in .all of such pockets. For the pur poseof effecting this result with he best po's sible' advantage we prefer to make the inner conveying. surface of the tube of greater width than the length of the operative parts of the briquette forming rolls; th' t is to say", of such cross sectional area that by nopossibility canthere be an accumulation of dust on the inner surface of the tube'fll which shall project over the workin'g'faces of the rolls 9, 9, thus assuring at all times the fact that as the material descends it 'will 'abso' lutely fill all. of the briquette forming pockets. .On the pair of rolls .9, 9,'there are two fla'nges'fi. 9, extending beyond the ends 'of the roll. They are shown as located on one of the rolls.- The inner surfaces of these flanges are flush with theoliter'edge of the eninne'r'surfacesare also flush withthe inner lower surfaces of the hogperi 10,'as shown in Figs. 1':and2.' Theseanges" come in con tact withthe material resting-on the-rolls and extending up into the -"hopper,iand serve todrag the material into the rolls adjacent to the hopper, thus feeding the; material ;to the ockets which are located near the the rolls, -and assurin .]a' proper supgly of material toflthese poc 1 12 represent intermeshm gear-wheels geari wheels being of the aftsa'n'd t to the that shift bythe PM tliat screws 1, keyed this gear-Wheel and its adjusting sleeve are thus keyed to one of the shafts 8 the angular relation of that. gear-wheel to the other gearwheel may be varied by shifting the adj usting screws 1?, l? at, will, these adjustable devices l r relation off the rolls or drums 9. 9,

as 1 ill be apparent on inspection of the drawings. Y

In 1' 8 and 9 we have illustrated the detail structure of the rolls or drums and the manner or" constructing the same. each drum consisting of a series of hollow circular disks l9 of'the same general nature as those disclosed in the before-mentioned U. Patent lilo. 718.043. except that in the pres ent instance said-disks are first cast in the manner shown in Fig. 8 with a series ofcomplete integral pockets '20 in. their outer or edge faces having each the conformation of the frustum of a pyramid with a rounded apex or top and rectangular base. After they are thus cast with relatively heavy marginal surfaces 21, 21 upon the side faces of the disks, they are then placed in a planer and these surfaces planed oil so that the lateral edges of the pockets on both sides assume a knife-edge conformation. The edges between the pockets are dressed with a tool to the sharpest possible condition. These disks being each provided with a spline 22 are then grouped and bolted together upon the shafts 8 in the same manner as disclosed in the above-mentioned patents so that all of the edges of the pockets are in alinement with each other, both tangentially and radially, and by this means we are enabled to produce a roll or drum in which the-completed pockets are absolute duplicates of each other throughout the entire surfaces of the rolls and arev located in such relation to each other that the nicest cutting efl'ect is had in the dividing up of the material as it is fed forward during the-process of. the making of briquettes. When these disks are assembled the shafts 8; 8 the edges of the pockets are all in alinement in planes in each direction,

' that by reason or the adjustable means illusso nicest adjustment of the rolls mav be effected trated in detail inFigs. Elto 7 inclusive the so as lo bring about the alincment of the chine we are l-inife edges of the several pockets of the two rolls as these edges pass by each other at the i elemenfsal or tangential line.

briquette making maand also of such structural form that est possible strength 1s given thereit not only an article which constituting means for varying the" ll; will also be apparent Y life ascertained that in the use of I enabled to produce a briqucttc like that illustrated in l0 and 11 of the drawings, each having the cleanest possible suri aces and edges and one in which the den-, sity is practically. constant throughout its 7 bustion eflect. The form of this briqucttc is, as will be obvious on inspcctlonof Figs. 9 and 10, that of the frustums of two pyramlds havmg tllGll rectangular bases integrally united. while the frustum ends thereof are slightly rounded.

e do not limit our invention to the details of construction illustrated in the accompanying drawings and l'lcl't'lnl'lcffil'c described. as a number of the features thereof may be materially departed from and still come within the scope of our claims hercinafter. To illustrate. various modified means might be devised for vetlccting the relative axial adjustment of the rolls or lrums f). 9, from that illustrated in igs. 3 to 7 inclusive. and other means than the tube 11 might be utilized for distributing the material as it is fed forward in the manner described; and our claims are of the most generic nature as to these features. "We believe it is also broadly new with us to construct a pockets in the edge face of each of the disks,

and that it is also new to provide a briquctte making machine of the drum type with a pyramidal shaped feeding means in the nature of thefrustum of a pyramid. the base of which is of greater width than the length of the rolls, whereby all of the briquette forming pockets will be filled at all times with the proper amount of material to construct perfect briquettes when the machine is in operation.

Ha ving thus described our invention what we claim and desire to secure by Letters Patent of the United States is' 1. A briquette making roll, composed of a plurality of circular disks, each disk having a single peripheral row of pockets on its edge surface, the pockets being complete in each disk, and there being a like number of pockets in each disk, each pocket; extending entirely across the disk. and producing a sharp utt ing edge in conjunction with the adjacent pocket onthe abutting disk.

2. A briquette making machine provided with two forming rolls composed of disks having complete or integral-pockets in the outer face ofeach disk and all supported upon parallel intergeared shafts: in combination with means' for varying the angular relation of the surfaces of the rolls, substantially as described.
